Prime number mazes

Mazes where you may only step on prime numbers, with one route and no guessing.

About this worksheet

Students find the path from START to END by stepping only on prime numbers. Every other square holds a composite number or 1, including look-alikes such as 51, 57 and 91, so each square needs a real check.

Every maze has exactly one route. Choose primes up to 30, 50 or 100 and the size of the maze. The answer key shades the route.
